We provide a general overview of the velocity-dependent one-scale model for cosmic string evolution and discuss two further extensions to it. We introduce and justify a new ansatz for the momentum parameter k, and also incorporate the effect of radiation back reaction. We thus discuss the evolution of the basic large-scale features of cosmic string networks in all relevant cosmological scenarios, concentrating in particular on the ``scaling'' solutions relevant for each case. In a companion… 
Dynamics of junctions and the multitension velocity-dependent one-scale model
The dynamics of string junctions and their influence on the evolution of cosmic superstring networks are studied in full detail. We review kinematic constraints for colliding strings in a
Extending and calibrating the velocity dependent one-scale model for cosmic strings with one thousand field theory simulations
Understanding the evolution and cosmological consequences of topological defect networks requires a combination of analytic modeling and numerical simulations. The canonical analytic model for defect
Long-term dynamics of cosmological axion strings
We present results of new field-theoretic simulation of cosmological axion strings, which are eight times longer than previous ones. We have upgraded our simulation of physical strings in Hiramatsu
Scaling properties of cosmological axion strings
High resolution calibration of string network evolution
The canonical velocity-dependent one-scale (VOS) model for cosmic string evolution contains a number of free parameters which cannot be obtained ab initio. Therefore it must be calibrated using high
Cosmic String Evolution in Brane Inflation
There has been notable effort in recent years to obtain inflationary models from string theory. In the most well-studied scenario, brane inflation, the inflationary phase typically ends with a phase
Quantifying the effect of cooled initial conditions on cosmic string network evolution
Quantitative studies of the evolution and cosmological consequences of networks of cosmic strings (or other topological defects) require a combination of numerical simulations and analytic modeling
Cosmological stretching of perturbations on a cosmic string
We investigate the effects of cosmological expansion on the spectrum of small-scale structure on a cosmic string. We simulate the evolution of a string with two modes that differ in wavelength by one
A Boltzmann treatment for the vorton excess problem
We derive and solve a Boltzmann equation governing the cosmological evolution of the number density of current carrying cosmic string loops, whose centrifugally supported equilibrium configurations

Quantitative string evolution.
TLDR
This generalized `one-scale' model provides a quantitative picture of the complete evolution of a string network, including the prediction of previously unknown transient scaling regimes and a detailed analysis of the evolution of the loop population.
